Town invasions are fun, however they pose little challenge. Can we get a them rescripted to the Evolution level? Drop some real meanies in there! Dunno what exactly, that's up to you. Can u just ramp them up like 100% =P
The invasions are meant for new-med level players with little risk as a "training ground" for novice players. We do have plans to add an automatic invasion and siege in a castle setting
